although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-newtonian calculus. the important point to note is that the non-newtonian calculus is a self-contained system independent of any other system of calculus. since this self-contained work is intended for a wide audience, inc...

Three experiments investigated the mental representation of meaningful event sequences. Experiment 1 used extended (5 min long) naturalistic scenes excerpted from commercial movies. Experiments 2 and 3 presented everyday activities by means of sequences of six photographs. All experiments found both left-right and distance effects in an order decision task, suggesting that when contemplated in ...

We present a new compression algorithm for video sequences of indoor scenes, or more generally, sequences containing mostly planar and near-planar surfaces. Our approach utilizes edge and optical flow information in order to segment selected keyframes into regions of general shape, such that the motion of each region is predicted well by a planar homography. With this kind of motion prediction,...

This paper describes an approach for automatically detecting action sequences in movies. We examine the filmmaking conventions that are inherent in action sequences and use these as a basis for our analysis. A system of lowmidand highlevel features is presented that combines pure digital video analysis at the lowand mid-levels, with high-level filmmaking knowledge. A state machine is used to co...

Angus2 is developed as part of a system capable of generating natural language output based on video sequences. Currently the video sequences in Angus2 is comprised of four scenes from surveillance cameras, two filming different crosswalks with pedestrians, one filming across a gas station, and one filming an intersection. Each of these video sequences features multiple objects and actors, that...

Continuity in level of detail sequences is essential in hiding visual artefacts that occur when switching between discrete levels of detail. However, construction and implementation of these sequences is prohibitively complex. We present a new structure, the g-mesh, which greatly simplifies the implementation of continuous level of detail in large scenes. We also introduce a novel greedy predic...

Can potentially antisocial or criminal behaviour be predicted? Our study aimed to ascertain (a) whether observers can successfully predict the onset of such behaviour when viewing real recordings from CCTV; (b) where, in the sequence of events, it is possible to make this prediction; and (c) whether there may be a difference between naïve and professional observers. We used 100 sample scenes fr...

This paper presents a new traffic model for MPEGencoded video sequences. The hybrid Gamma/Pareto distribution is used for all three types of frames in MPEG-encoded video sequences, and the present model takes scene changes into account. The autocorrelation structure is modeled using two second-order auto-regressive (AR) processes nested with each other. One AR process is used to generate the me...
